Problem:
Wireless Internet is going incredibly slow, also random latency spikes. Both my Laptop and Desktop are connecting to the same internet source, both via wireless. The desktop is experiencing very slow internet connection, while the laptop is showing much faster results.

Attempted Solutions:No Change - Using drivers on the disk which came with the Wireless Adapter.
No Change - Updating to the latest drivers on the Linksys website. (Their latest drivers are from 2005 for this adapter...)
No Change - Running Troubleshooting.

Hey, Linksys is asking me for version, FYI look at this screenshot for more info. Whats your version? I guess u gotta open up your computer case... Coz the two different versions have two different drivers....

Have you tried rebooting the router? (switch off for 30secs) What router do you have?
No real change with rebooting the router.
I have a Netgear WGT624 v3: WGT624 - NETGEAR.com

First welcome to Sevenforums. Are both the destop and laptop running win 7? are they both on the same homegroup? Are they both getting dns/dhcp from the linksys or is the IP fixed?

Thanks for filling out your system specs and we just need some more info to be able to help. Someone here will have the answer.
Sorry I couldn't be more help so far

Are they both on the same homegroup?
Win 7 says the Desktop is connected to a homegroup. However, I do not remember setting it to be connected to a homegroup. The Laptop is not connected to a homegroup to my knowledge.
Are they both getting dns/dhcp from the linksys or is the IP fixed?
I am not 100% sure how to check if they are both getting it from the linksys. However when looking at the Network Connection Details for both the Desktop and the Laptop it says "DHCP Enabled... Yes" for both of them. If anyone is willing to let me know how to find out this information I would be willing to get it.

Additional Details:I plugged in a Wired cord to my desktop with Windows 7 as a temporary setup, the internet speeds increased by a lot. This leads me to believe that I either have a bad wireless card or there are problems with my cards compatibility with Win 7. Here is the speed test of my Desktop with Win7 and a wired connection: https://www.speedtest.net/result/498167366.png

What I would connect up LAN cable (for internet access just for now)(YOU NOW MUST HAVE ONLINE ACCESS WITHOUT THE WIRELESS) then go to Device Manager>Expand 'Network Adapters'>Right Click on the 'Linksys ...">Uninstall>If you see the "delete driver option" Check that>then press OK.

Then right click 'Network Adapters'>Scan for hardware changes>Windows should now detect the 'Linksys PCI...'>Click on the 'Installing Device Driver Software'>Wait for it to complete>Now check if it works nicely

Once done updating Intel Chipset Driver, now see whether there is a difference in speed... if not read the bottom part

UPDATE: A google search said a LOT of people have the same problem. i used the term 'Vista' instead of '7'>the i saw this guy (he claims to have v4.1) View he's post: http://www.frihost.com/forums/vt-103681.html
IF you want to try he's driver(download and extract it) then do this: Go to Device Manager>Expand 'Network Adapters'>Right Click on the 'Linksys ..." Update driver Software>Browse my computer manually...>Browse>the folder u extracted to has a Vista-x64 folder (SELECT THAT)>Next>Hope this works....

With a wired card I get 6.5Mbps
With a wireless card I get less than 0.5 Mbps.
With a wireless laptop in the same physical location, via the same router I get 6.5 Mbps.

I've tried three separate wireless network cards; TP-Link, Netgear and D-Link. The Netgear one has issues with more than 2Gb of RAM and won't install the drivers. The other two are both on the latest up to date drivers, and still refuse to give me higher than 0.5 Mbps.

I even disabled encryption on the router when someone mentioned that might work. It made no difference.

Win 7 - Slow Internet

Desktop WIFI Internet Issue - Connected, but Slow/Dropped InternetI've been battling this particular issue for a couple of weeks now without much success. I have a custom built desktop where my WIFI connection will deteriorate to the point where internet (and gaming over Steam, etc...) will be either painfully slow or unable to load pages at all. Windows claims...

Network & Sharing

Constantly slow and disconnecting from internet (no internet access)Ok this has been happening for a few weeks now with the connection either being slow or just displaying a yellow triangle saying limited access and no internet access. Getting pretty desperate and running out of ideas now so need to ask here.
Basically we switched ISPs after about a month of no...

Network & Sharing

Slow browser, slow internet, random audio ads: virus?So yeah, I've these problems for the past couple days. My browsers (Opera and Firefox) used to load pages quickly, but now they're painfully slow. Opera lags and freezes often; Firefox doesn't, but it still takes a very long time to load pages.
I'm also getting these occasional "invisible ads,"...

System Security

Slow internetNow, my computer's internet goes fairly fast. However, when my sister turns on hers, and starts to download files, my internet level starts to drop significantly. I, then, start to experience connection, which is annoying. I heard something about limiting bandwidth, however, I can't find that on my...

Slow internetMy internet is sooo slow. My WiFi has always been slow but I use Ethernet for my laptop and youtube videos dont load at all. Everything was working fine up until a few days ago when I messed with the router settings to get wifi to work better. Its pissing me off because the other two computers in...
